To all 107mm it WZ/(Q/ concern v Be it known that l, Pii'unr S. Chins, a citizen oi the United States, residing at Detroit, colony of ll ayne, State of Michigan, have invented a certain new and useful l nr provennint in Internell-Combustion Engines, and declare the following to he a full, clear, and. exact description of the same, such. as will enablev others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to internal comhuslion engines and an object of my. invention is to provide an iniprmed engine of this type and one in which the control of gases passing tln'ough the. engine is improved and evenness of wear in the cylinder secured.

l attain this object in the device illusi L n view of a one of the cylinders.

i the crank case, andv B, isa cylinder a water'- jacket. G. is a. distance piece uniting the cylinder ll with the crank case A. The distance piece U contains a casing for the gearing hereinafter described l is a cylinder fitting in. the cylinder B and the distance piece C, and adapted to reciprocate and rotate therein.

E, is a piston adapted to reciprocate in the cylinder D.

la", is a connecting rod, the upper-end of w ich is connected to the piston F. by a universal joint, or, as shown in Fig. l, by a ball and soclfet'joinl, the connection being such as to permit the oscillation of the connecting rod and the rotation of the piston. lhe lower end of the connecting rod F is connected t'o'the main shaft G of the engine by the usual crank.

H, is a counter shaft resting in hearings in portion oi the top of hpecification of Letters Patent.

the crank case A parallel to the main shaft of the engine. The shaft H is connected to the main shaft by a sprocket gearing, in the present instance, the chain of which is indicated by the reference letter T.

l, is a-connecting rod, its upper end connected to the lower end of the cylinder D, by being pivoted to the ring Z, which ring is included between two annular lugs e 2 ex-- cept in the form shown in Fig. where the gear S takes the place of one of said annular lugs. The lower end of the connecting rod lconnected by an eccentric mechanism to the shaft H.

J, is an aperture through the upper part of the vertical walls of the cylinder 1). The aperture .l may register with the intake port M to permit the in-drait of explosive mix ture, or with the exhaust port N to permit the exit oi theproducts of combustion.

K, is an aperture similar to the aperture J through the vertical wall of the cylinder D just above the position atwhich the upper. end of the piston comes at its lower dead center. The aperture K is adapted to register with an auxiliary intake port L or with an auxiliary exhaust port 0. The exhaust ports N and O communicate with the same pipe from which leads an exhaust pipe P.

(.2, is a helical gear wheel upon a shaft It i which is connected by a chain, 25 with the main shaft of the engine.

S, isan annulus having teeth with which the teeth of the gear wheel W engage.

The operation of the above described device is as follows: When the engine is running, the cylinder D is continually reciprocated by the connecting rod 1 geared to the main shaft of the englne. The cylinder'is at the same time rotated by the gear Q, which. is also geared to the engine shaft. Thus the cylinder D has two motions, one of reciprocation and one of rotation. The apertures J K are made slanting, as shown, and the ports M and L are made of corresponding form so that the sides of said apertures and ports are at right angles to the motion of the cylinder due to its reciprocation and revolution, thus the ports are opened and closed rapidly. There may of course be a number of apertures J and K to correspond to the cycle of the engine and speed of rota tion of the cylinder D. The rotation of the cylinder Dazed its reciprocation. to ether change the angular position relative to the cylinder D so that the wear shall not be all the apertures ll V Y inthe top of the cylinder B as the cylinder 1) rotates. Thus the sparking plug which passes through the aperture U in the cylinder B may extend through the aperture lV into the cylinder l) to ignite the charge therein. "An oil supply apparatus may be placed in the aperture V and the discharge from this apparatus may pass through the aperture X. priming cup may be placed at Y above the path of the apertures W and K so that the hydrocarbon may be allowed to pass therefrom into the cylinder D to start the engine.

In the modification shown in Fig. 5, instead of a helical gear S, l have shown a gear 55' with straight teeth and the motion is communicated from the crank 'sha'lt G by the bevel gear wheel 7) the .shait. c and spur gear wheel (Z.

In the form of device shown in Fig. 6, l have provided the cylinder D with a slot m into which extends a stationary plug n. The reciprocation or" the 'cylinderll will now give the said cylinder a limited rotary, or an oscillating motion, and a longitudinal or reciprocating motion, this being a different way of accomplishing the same result, as shown in the first form of device. Thus'l wish it to he understood that when l refer to a rotary motion I include an oscillatory motion as one form 0* rotary motion.

' In the term of device shown in Figs. 1) and 6 the upper end of the inner cylinder is closed and an aperture \V is formed in its side wall, which aperture s closed'by the wall of the outer cylinder, but, when the explosion takes place is directly opposite the sparking plug extending through an aperture in the side of the outer cylinder in the usual way. i In this form of device the explosion chamber is entirely within the inner cylinder and the motion of the inner cylinder is so adjusted as to make its head approach the upper end of the piston at the 1. In an internal combustion engine, a

cylinder, at second cylinder having one end closed adapted to reciprocate in the first named cylinder, ports through the wall of the first named cylinder, an aperture through the wall of the second cylinder adapted to register with said ports, a piston adapted to reciprocate in the second cylin der, and means for giving the second cylinder a movement of rotation and reciprocation whereby the motion of the second cylinder controls the passage ,of gas there through. i

In an internal combustion engine, a cylinder, a second cylinder having one endclosed adapted to reciprocate in the first named cylinder, ports through the wall of thc first named cylinder, an aperture through the wall of the second cylinder adapted to register with said ports, a piston adapted to reciprocate in the secondcyiinder, and means for giving the second cylinder a movement of rotation and reciprocation whereby the motion of the second cylinder controls the passage of thercthrough, the reciprocating motion of said second c vl indcr being timed with reference to the movement of said piston so that the residual gases shall be completely expelled at the end of the exhaust stroke.

In an internal combustion engine, a cylinder, a second cylinder having one end closed adapted to reciprocate in the first named cylinder, ports through the wall of the first named cylinder, an aperture through the wall of the second cylinder adapted to register with said ports, ton adapted to reciprocate in the second cylinder, and means -tor giving-the second cylinder a movement of reciprocation wherebythe motion of the second cylinder controls the passage of gas therethrough, the reciproeating motion of said second. cylinder being timed with reference to the movement of said piston so that the residual gases shall he completely expelled at the end of the exhaust stroke.

In testimony whereof, I sign this specifi cation in the presence of two witnesses.
